Installation shall be in accordance with the manufacturer’s
instructions or warranty may be voided.
IMPORTANT
Operation of the Taco On Command without being plumbed into water lines may dam-
age the pump and void the warranty.
2. Tools you need:
• Pipe or crescent wrench
• Phillips and flat head screwdrivers
• Plier
• Drill and
5
⁄
8
inch drill bit
• Wire strippers
3. Best location for the Taco On Command:
Typically, this would be at the fixture farthest away from the water heater, generally the
kitchen or master bath room. If your hot water supply runs in two different directions
from the water heater, you may need more than one Taco On Command.
PUMP POSITION
Pump should always be installed in a horizontal
position (as shown) with On Command capacitor
box facing up toward the sink. Be sure arrow on
pump casing is pointing from left to right (hot water
to cold water side) prior to connecting the flex lines.
Note: T’s and flex lines supplied by Taco provide
maximum flow and performance. Alternative
plumbing parts may restrict flow and delay hot
water to fixtures.
WARNING: In the event the retaining screws have been pulled out of the hous-
ing, DO NOT replace them. Use of any other screw may short out
the stator windings, creating a risk of electrical shock.
WARNING: To avoid electrical shock, disconnect the power supply to the cir-
culator and the main electrical unit.
CAUTION: When installing electrical connections, do not apply mechanical
loads to the capacitor box; otherwise, retaining screws may be
pulled out of the housing, making circulator unusable.
